Application filed April 1?, 1914. Serial No. 832,567.

To all M am it may. concern:

Be it known that 1, Lewis E. lVA'rmiMAN,

vators adapted to cultivate a plurality of rows of corn or other growing plants at one operation.

One of the primary objects of this invention is the provision ofa cultivator which can be easily manipulated and shifted by the operator so that the earth agitating devices. maybe made to follow the rows and can be quickly and easily shifted .as occasion requires.

Another object of the invention is the .pro-

vision of a cultivator inwhich the arches, to which the cultivator beams are attached, serve as a support for the beams, also as a connection between the wheels by means'of which the wheels are maintained in parallelism, and by means of which they may be angledand also comprise a part of the lifting mechanism for raising and lowering the beams.

A, further object is the provisionof'novel means for adjustingor levelin the beams vertically so that the various eaith agitating devices carried by each beam will dig to the required depth relativelyto-the other devices on the same beam when thecultivator. is in operation. x

Another object is the provision of improved means for tilting the beams so as to" elevate the rear ends thereof above tl'I-G fOIP ward ends when the beams are raised to inoperative position. i I

A further object is to mount the poles on the cultivator frame in a novel nanner and I to connect them up with the beam and wheel.

considered in connection with the accompanymg drawings.

Referring to thedrawmgsFigure 1 is a plan view of a'cultivator embodying'my invention; Fig. 2 is a front view partially in section taken substantially on the line 2-2 of Fig. 1; Fig. 3 is a rear view. of the machine, taken on, the line 33 of Fig. 1; Fig. 4: is'a side elevation with the wheel removed. this view being taken on the line 4-4: of Fig.1; Fig. 5 is a fragmentary sectional view on the line 5.-5 of Fig. 1; Fig. 6 is a fragmentary plan view of the machine. certa n parts being broken away to more clearly lit) disclosethe portions lying underneath; F in:

7 is a transverse sectional view taken on thilin 7-7 of Fig. 1, and Fig. 8 is-a detail view partially in section 'of the connection 2wtween the outer end of the yoke and its corresponding angling arm.

By reference tothe drawings it will be observed that the main frame of the machine comprises a rear member 9, preferably formed of angle. iron, and a front member 11 of substantially U-shape, also formed of angle iron and connected at its rear end with the rear member 9 through the intermedmry of supporting brackets 12, of angle shape,

rigidly. bolted to the two members of the frame. Each supporting bracket is formed to provide a vertically disposed journal bearing 13 in which the vertical member 1. of asupporting standard'is pivotally mount.- ed toswing about the vertical axes. The lower end-of each standard is'formed to pro vide a laterally projecting axle 15 upon which asupporting wheel 16 is mounted and a forwardly projecting arm 17, which is preferably inclined downwardly, ,as shown in Fig. 4, and has its extremity upturned and provided with an integral ball 18 shown in Figs. 6 and 8. Thearms 17 may be con.- struct'ed integrally with the standards,'if preferred, but in the form that I have shown for purposes of illustration the arms are clamped to the standards just above the axles 15 and are shaped to seat over the axles as shown in Fig. 4 so that a rigid Connection between the arms and the standards is secured.

Upon the rear member 90f the maih frame I have mounted intermediate its ends, and preferably centrally thereof, a bracket 1'9 provided with an opening to receive'thevertically disposed bearing portion llifio f a ward member 11 of the main frame at its front end and provided at its rear end with a bearing opening to receive the crank member. Lateral brace members 24 and are bolted at their upper ends to the frame member 9 and at their lower ends to the brace An upper brace 26 surrounding the crank member above the bracket 19 and attached at its forward end to the main frame member 11 serves to strengthen and lend rigidity to the crank member mounting. A bracket comprising a journaled portion 27 surrounding the crank 22, and a bridge portion 28 resting upon the horizontal arm of the crank member, is rigidly connected by bolts or other suitable means with seat supporting arms 29 carrying at their rear ends the seat 31. A. link 32 connected at its rear ends with the arms 29 by bolt or p'in and pivotally associated with the upper end of the crank member 21 serves to sustain to a large extent the weight of the operator on the seat. It will be manifest that the seat is pivoted to swing about the bearing portion 21 of the crank member and that the crank 22 has a pivotal connection with the bracket to which the seat supporting members 29 are attached so that a limited relative movement between the bracket and the crank is afforded which permits lateral swinging movement of the crank about the bearing portion 21.

The seat supporting members and the crank tral bracket. It will be observed from Figs.

(3 and 7 that the journal portion 27 is provided with a forwardly extending lug 37 to which the inner ends 3!; of the arches are pivotally connsuted by a bolt 38. The outer portions 36 of the arches are equipped with socket members 39 which fit over the balls 18 of the standard arms 17 and provide a ball and socket connection between each arch and its respective standard. It will be manifest that the construction just described provides a .connection between the standard arms at opposite sides of the machine which maintains the supporting wheels 16 in parallelism and that upon swinging movement of the seat support the arches will be shifted laterally in one direction or the other with respect to the main frame and tl'nrough the intermediary of the arm 17 will impart this shifting movement to the wheels, with the result that the wheels will both be angled in the direction of movement of the arches. The cultivator beams all, by which the earth agitating devices of any Well known or preferred construction (not shown) are carried, are supported at their forward ends upon the horizontal portion of the arches. The details of the means by which the beams are supported from the arches will be later described.

' From the foregoing it will be obvious that the arches perform a dual function; namely, they support and carry with them in their lateral shifting movements the cultivator beams and also form a connection between the wheels by means of which the wheels are angled or shifted simultaneously with the shifting of the beams. The arches, however, have still a third and a very important function in that they serve in conjunction with other mechanism which will now be described as a means for raising and lowering the beams. At the rear end of each pole L2. to which the horses are attached, I have mounted a. notched segment 43 and have pivoted upon a bolt Aan operating lever 45 equipped with the usual manually controlled latch +6 adapted to engage in the notches of the segment 4-3. A link 47 is engaged at one end with the crown of an arch 3i and pivotally connected at its other end by a bolt 48 with a plate 49 secured to the lever if). It will be manifest that the movement of the lever 45 rearwardl y, or, in other portions 35 of the arches and upon each sleeveis clamped, by means of a clamping bolt 52, an u iwardly projecting arm 53 provided with rearwardly disposed journals 54. The forward end of each beam. is provided with an upstanding portion 55 pi votally engaged. in the journals 5% and a clamping ring 56 secured to the upstanding portion 55 by a set screw interlocked with the upper journal 54 to support the beam in position. beams are therefore pivoted to the arms 53 to swing in a horizontal plane.

In order to hold the beams in substan tially vertical position, I ha re provided mechanism which will now be described. Upon the front frame member 11 I have secured substantially in alinement with eacharm 53 a downwardly projecting member 57 provided with a plurality of apertures 58. The upper end of each arm 53 is also pro- The "1 Ward tilting movement.

vided with. an aperture and a link connection 59, including a bolt 61 passing through the upper end of the corresponding arm 53, which serves to hold said arm against rear- The hand nut" 62 is adjustable thereon on'the bolt 61 and this "nut may manuallyadjusted when the beams are in operative position to level the beams so that theearth agitating devices will be disposed in .the same plane, or, if pre-' fcrred, infan' inclined plane to. dig the re- 'quired depth. Y

i illustrates the position of the parts when the bears are in operative'position and it will be noted that the beam 41 shown is substantially horizontal while the arm 53 I is substantially vertical.

that by manipulating the nut' 62 the rear It will be obvious end of the beam may raised; or lowered as required; This link connectionbetween the arm 53 and the frame also serves the further purpose of elevating the rear end of the frame higher than the forward end Whe the beam is bodilyv raised through the instru'mentality of the arch and the operating lever. It will beobvious from an inspection of Fig. 4: that as the arch is swung upwardly about its pivotal connections with the arm 17 and the central bracket" 27 the arm 53 will be carried upwardly with the arch. The connection between the upper end of the arm 53 and the member 57 will,

thereby elevating the agitating devices sufficiently'so that they will pass over stones, stumps or other obstructions.

- In order to lend flexibility to themachineand render it easy to manipulate so that itcan be shifted laterally with ease and rapidity the pbles 42 are pivoted to the front member 11* of the main frame upon bolts 63 and a sliding connection between the poles and the rear member 9 is-established, suitableguide-rollers 64 being provided both above and beneath the horizontal web of the rear framevmember to reduce the friction and cause the polesto move easily along the frame. The movement of the poles is effected from the swinging seat supports through the brace 32 which projects forwardly beyond the bearing portion 21 of the bell crank member and is connected by links 65 with the poles disposed on each side thereof.

The beams are mounted in. parallel rela 'to each beam.

. and guiding the same in and lower said beams.

tion with each other by means of a bail-66 slidably supported in loops or eyes 67 carried by the rear ends of the poles 42, the bail being equipped with downwardly extending arms 68 slidably engaging in eyes 69 secured A. link 71 attached at one end to the bail and at its other end to one' of the poles serves to slide the bail laterally with'the poles. Links 72 suspended from the frame member 9 are connected with the two central arms 68 to assist in supporting their lateral shifting movements. It will be manifest from the foregoing that I have devised a cultivator in which the arches serve as a connecti n between the that the invention is not circumscribed by the details disclosed for purposes of illustration, and that while the invention is embodied in the present instance as a two-row cultivator it is capable of adaptation to a single-row, cultivator without departing from the spirit of the invention or sacrificinn" any of the material advantages thereof.
